PROBLEM TO BE SOLVED: To automatically suppress an unnatural rhythm generated by the expression that is not following a grammatical rule. SOLUTION: A first accent phrase generating section 23 generates an accent phrase based on the text analysis result of a text analysis section 21. A second accent phrase generating section 24 generates an accent phrase without depending on the text analysis result. An accent phrase generating discriminating section 22 allows the generation of an accent phrase in the section 24 based on the analysis result, when an inputted text is a speech. When the inputted text is a speech not following a grammar, an accent phrase is generated without depending on the text analysis result. Thus, the generation of an unnatural pitch pattern based on an incorrect text analysis result by the section 21 is prevented. |
